Author conclusions• Individual clonal growth rates can be used to estimate growth
dynamics after a fixed-duration treatment. • Clonal growth was lower after Ven-Obi than after Clb-Obi,
indicating more effective MRD eradication and clonal growth modulation with Ven-Obi.
• In a considerable subgroup (approx. 20%) of Ven-Obi treated patients, no clonal growth was measurable during observation, indicating deepest remissions.
• This translates into a sustained PFS benefit for several years after treatment completion, with a 4-year-PFS rate of 74% for Ven-Obitreated patients.

• Some patients have deep responses that deepen even further
• At EOT some were MRD+ (black box) – would more treatment help?

Chalk Talk – Dr Kahl
• The appeal comes if it facilitates time limited therapy
• More side effects encountered during dual therapy (personal experience in CLL and MCL)
• Theoretically possible dual therapy advantageous in scenarios of unfavorable biology (17p del, p53 mutated)
• No situation where I would do it outside a trial in CLL at present
Do you believe there is a benefit to administering BTK inhibitors and venetoclax in combination as opposed to sequentially in patients with CLL? Are there any situations in which you would do so outside of a clinical trial today?
Primary analysis of the Phase III GLOW Study: Fixed duration Ibrutinib and Venetoclax (I+V) versus Chlorambucil plus Obinutuzumab (Clb+O) for first-line CLL
• Patients aged ≥65 years or 18-64 years with cumulative illness rating scale (CIRS) score >6 or creatinine clearance <70 mL/min randomized to I+V or Clb+O
• All-oral, fixed duration I+V demonstrated superior PFS versus Clb+O as first-line treatment (HR 0.216, p < 0.0001)
• At 3 mo after end of treatment, rate of uMRD was significantly higher for I+V vs Clb+O in BM (51.9% vs 17.1%; p < 0.0001) and peripheral blood (PB; 54.7% vs 39.0%; p = 0.0259)

Primary analysis of the fixed duration cohort from the Phase II CAPTIVATE study of first-line ibrutinib + venetoclax for CLL
• First-line ibrutinib plus venetoclax, an all-oral, once-daily, chemotherapy-free fixed-duration regimen provides deep, durable responses in patients with CLL/SLL
• Benefit was observed regardless of genomic high-risk features.
• No new safety signals were identified

If you could access one of the novel noncovalent BTK inhibitors (eg, pirtobrutinib) for your patients with relapsed CLL today, would you want to use it in clinical practice?
Yes: In second line, ibrutinib failure
No
Yes: Would prefer it over idelalisib
No
Yes: Far better BTK inhibitor, will be drug of choice when
approved
Yes: Covalent BTK refractory
Yes: BTK failure c481 mutated
Yes: Covalent BTK refractory
Yes: For BTKi-resistant patients
Yes: Generally post covalent inhibitor with progression

• Attractive when encountering intolerance to 1st and 2nd generation BTKi
• True for CLL and MCL and WM and MZL
• RCTs will determine whether 3rd generation will supplant 1st and 2nd
generation
If you could access one of the novel noncovalent BTK inhibitors, would you want to use it in clinical practice? For which type of patient would you be inclined to use these agents?

Agenda
MODULE 1: Chronic Lymphocytic Leukemia• Choice of front-line therapy• Selection of a BTK inhibitor• Second-line therapy• Third-line therapy• Ongoing research: Combination strategies, noncovalent BTK inhibitors,
CAR T-cell therapy
MODULE 2: Follicular Lymphoma• Selection of first- and second-line treatment• Third-line therapy: Tazemetostat, PI3K inhibitors, CAR T-cell therapy
Regulatory and reimbursement issues aside, what would be your most likely initial treatment choice for a 78-year-old patient with Stage III, Grade I or II follicular lymphoma (FL) with fatigue and symptomatic bulky adenopathy who required treatment?
Rituximab/lenalidomide

Do you believe community-based oncologists/hematologists should be presenting the R2 regimen of lenalidomide/rituximab as a front-line option to patients with newly diagnosed FL?
• Patients with bulky/symptomatic low-grade lymphoma should be treated with combination regimens.
• RELEVANCE study compared R-Chemo to R2 in untreated FL.• Overall response rate and progression-free survival was excellent (and similar) in both arms.• Lenalidomide combination has more rash, chemotherapy had more neutropenia and severe
infections.• No increased risk of secondary cancers was seen in either arm.• Treatment should be individualized for each patient.

Regulatory and reimbursement issues aside, what is your usual second-line therapy for a 65-year-old patient with FL who achieves a complete response to 6 cycles of BR but then experiences disease relapse 4 years later?
1. Re-treatment with BR2. Obinutuzumab/bendamustine3. R-CHOP4. Rituximab/lenalidomide5. A PI3K inhibitor6. Tazemetostat7. Other

What is the optimal therapeutic approach for a patient with FL with and without an EZH2 mutation who has experienced disease progression on bendamustine/rituximab and then R2?
• Several effective options exist for patients with relapsed FL.• Single agent anti-CD20 agents• EZH2 inhibitors (also effective in EZH2 wild type disease)• CAR-T• Auto SCT• PI3K• Clinical trials (anti-CD19, BiTE, anti-CD47, anti-Syk, BTKi)
• Always repeat a biopsy to confirm the dx and exclude transformed disease.• The selection of next-line therapy should be informed by patient’s prior disease course
and length of prior remissions.• Helps understand patient’s short- and long-term risk from FL.• There is no “right answer.”
Chalk talk – Dr Fowler
Do you believe that there are discernible differences in terms of efficacy or tolerability that make one of the four FDA-approved PI3K inhibitors for relapsed/refractory FL a better therapeutic option?
• Currently approved PI3K inhibitors are associated with remarkable and similar efficacy.• PFS ranging from 10-11 mo.• ORR of around 50%.
• Different isoforms and drug structures have resulted in very different toxicity profiles.• ↑↓ colitis, infection, hyperglycemia, hypertension and rash.
• Patients should be counseled on the potential risks as well as how to manage side effects.• Especially infection risk and GI side effects.
• Dose interruption and/or reduction is effective and often allows for re-starting the drug.• Choice of drug should be individualized.• Ongoing studies looking at different schedules to reduce toxicity look promising.

• High and durable response rates were observed in patients with aggressive (n=28) and indolent R/R NHL (n=24) who had failed multiple lines of therapy and who were treated with the bispecific antibody glofitamab
• CRS, the most common adverse event, was mostly manageable

• Phase I/II Study: patients with R/R CD20+ B-NHL (FL n=12, DLBCL n=46, MCL n=4, others n=6) were treated with subcutanouesepcoritamab, a bispecific CD20xCD3 antibody
• Epcoritamab demonstrated substantial single-agent activity, inducing deep and durable clinically meaningful responses, with a consistent safety profile.
